"Juan1" is a new japonica rice variety of mid-late maturing, tolerance to lodging and adaptable to direct seeding which was developed by the rice breeding team of National Institute of Crop Science, RDA, in 2005. This variety is derived from a cross between Ilpumbyeo, a variety of good-eating quality and high yield, and SR18392-HB683-104. The Juanl has heading date of August 19 at ordinary planting in the middle plain. It has semi-erect plant type with culm length of about 80cm and tolerance to lodging. This variety shows susceptible to blast, bacterial blight, virus diseases and brown planthopper. The milled rice kernels of Juanl are translucent with non-glutinous endosperm, clear in chalkiness and medium short grain. It has also low amylose content of 18.8%, low gelatinization temperature and good palatability. The average milled rice yield of this variety was 5.68 MT/ha at ordinary planting in local adaptability test for three years from 2003 to 2005. Juan! would be highly adaptable to middle plain and mid-eastern coastal region of Korea.

"Seolhyangchalbyeo", an aromatic and glutinous rice cultivar, was developed by the rice breeding team of National Crop Experiment Station, RDA during the period from 1991 to 1999 and released in 2000. The cultivar is derived from a cross between Miyagaori

“Undoobyeo” is a japonica rice cultivar (Oryza sativa L.) developed by the rice breeding team in the National Crop Experiment Station, RDA, Suwon, Korea in 1998. Undoobyeo was derived from a cross between Odaebyeo and Jinbu 13 made during 1989/'90 winter

Kwanganbyeo is a japonica rice variety developed from the cross between Namyang 7 and SR14779-HB234-31, anelite line derived from the cross between Cheonmabyeo and Aichi 37 at the National Crop Experiment Station, RDA, and washi-tecture and light-dark gre

Junganbyeo is a japonica rice variety derived from a cross of Namyang 72* Hapcheon 1 by the rice breeding team ofNational Crop Experiment Station, RDA, in 1999 and was released in 2000. This is a medium-early variety with growth durationtdark gren leaves.

Andabyeo, a new Tongil-type rice (Oriza sativa L.) cultivar, is developed by the rice breeding team of National Cropbetween SR11532-4 and SR14502F2. This cultivar has about 115 days of growth duration from seeding to heading and is semi-dwarf (culm length

The natural pigment Cyanidin-3-glucoside (C3G) content of rice bran was analyzed with different polishing degrees in pigment layer of Heugjinjubyeo produced at National Crop Experiment Station in 1999. The general composition of rice bran of Heugjinjubyeo

The content of anthocyanin, cyanidin 3-glucoside (C3G) and the peonidin 3-glucoside (P3G) from 591 rice cultivars and the antioxidative activities of MeOH extract from 8 rice cultivars were evaluated. Among them, C3G content of pigmented rice were ranged from 0 to 451.9mg in 100 g brown rice, while the P3G contents were in the range from 0 to 42.7mg in 100g brown rice. There was no correlation between C3G and P3G content. Total anthocyanin content ranged from 0 to 475.1mg in 100g brown rice. The antioxidative activity, the scavenging activity on DPPH (2,2-diphenyl-picryl-hydrazyl) radical of MeOH extracts from rice grain, were different according to cultivars. The activity of blockish purple pericarp rice cultivars was twice stronger than that of white pericarp cultivar. Especially, the antioxidative activity of Heugjinjubyeo was four times stronger than that of white pericarp cultivar. The scavenging effect on DPPH radical in rice extracts was related to the total anthocyanin contents of the extracts.
